我是htaccess和重定向的新手，我希望有人能帮我。目前所有的http网址都能正确重定向。例如，如果你去otherdomain.com，它会把你带到maindomian.com。
这目前并不适用于所有https链接。
例如：http -www和非wwwotherdomain.com/blog都将重定向到https://www.mainwebsite.com/blog
这是我所需要的，然而，只要我到了https它做以下：
https-www和非otherdomain.com/blog都将保留在httpsotherdomain.com/blog域上。
这是错误的，因为它需要转到主网站的博客页面。但如果我手动添加了一个页面上的重定向，所有的http和https网址将工作：例如，www和非www http://www.otherdomain.com/newpage将重定向到https://www.mainwebsite.com/welcomehttps://www.otherdomain.com/newpage将重定向到https://www.mainwebsite.com/welcome
这是Drupal 7，这是我目前拥有的代码：

Redirect /newpage                                       https://www.mainwebsite.com/welcome

    RewriteEngine on
    RewriteBase /

    # Force HTTPS 
    RewriteCond %{HTTPS} off
    RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

    # Remove trailing slash
    RewriteRule ^(.*)/$ https://%{HTTP_HOST}/$1 [R=301,L]

    RewriteCond %{HTTP_HOST} ^mainwebsite.com$ [NC]
    RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

    # Set "protossl" to "s" if we were accessed via https://.  This is used later
    # if you enable "www." stripping or enforcement, in order to ensure that
    # you don't bounce between http and https.
    RewriteRule ^ - [E=protossl]
    RewriteCond %{HTTPS} on
    RewriteRule ^ - [E=protossl:s]

    # Make sure Authorization HTTP header is available to PHP
    # even when running as CGI or FastCGI.
    RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

        # Pass all requests not referring directly to files in the filesystem to
    # index.php. Clean URLs are handled in drupal_environment_initialize().
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} !=/favicon.ico
    RewriteRule ^ index.php [L]

我想知道如何从httpswww.example.com获得任何网址otherdomain.com，以转到mainwebsite.com?。任何帮助都将不胜感激。
